Is it safe to pass anonymous type to MVC ViewData.Model?

Is it ok to do the following:

View(new {Object A, Object B})

Or should Object A and Object B be explicitly declared in a new type?

Thanks.

Yes, it's fine to do so. To get the values, you can use ViewData.Eval("PropertyName") and the existing Html helpers will work fine with them. The only thing you won't be able to do is get strongly typed access to the properties using <%= ViewData.Model.PropertyName %>

I believe you want to at least give them names:

var model = new 
{
    ObjectA = new A(),
    ObjectB = new B(),
};


view(model);

By passing anonymous types you cannot have strongly typed views. You will also need to use reflection in your unit tests.

Although anonymous types are versatile for many MVC purposes, in this case I would use a regular named class, or at a push a dictionary (or the inbuilt one). Otherwise you will have to use reflection / TypeDescriptor to get the values out again.
